Rail assembly

ABSTRACT

A rail assembly has a bracket, a base, a rail body and at least one bolt. The bracket is securely mounted on a surface of a furniture and has a top surface, a fastening tab protruding from the top surface and at least one fixing hole. The fixing hole is formed through the fastening tab. The base has a bottom surface, a mounting tab protruding from the bottom surface of the base and at least one mounting hole, wherein the bottom surface and the mounting tab correspond to the top surface and the fastening tab. The mounting hole is formed through the mounting tab. The rail body is securely mounted on the base. Accordingly, the rail assembly can be conveniently assembled without using any tool.

BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to a rail assembly, and more particularlyto a rail assembly that is capable of securely and directly hanging on asidewall without using tools.

2. Description of the Related Art

Conventional rails are securely mounted between cabinets and drawerswith screws and have normally been assembled before furniture been sold.Thus, buyers do not need to worry about assembling problems of rails forthese finished-furniture. However, the finished-furniture is graduallyreplaced by Ready-to-Assemble (RTA) furniture since the RTA furniture isconvenient in use and reduces manufacturing, transport and storage costsand spaces. However, most of the RTA furniture still need tools whenassembling, especially for mounting metal parts on wooden plates, suchas mounting rails on inner surfaces of a cabinet. However, mounting therail on the inner surface of a cabinet at precise locations to makedrawer runs smoothly is not easy for a person who is not skilled inassembling furniture, since the rail is long and heavy but is not easyto leveled on a desired location when using screws to mount the railassembly on a surface.

The present invention provides a rail assembly to obviate or mitigatethe shortcomings of the conventional rail.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a railassembly to improve ease of assembling the rail assembly.

The rail assembly has a bracket, a base, a rail body and at least onebolt. The bracket is securely mounted on a surface of a furniture andhas a top surface, a fastening tab protruding from the top surface andat least one fixing hole. The fixing hole is formed through thefastening tab. The base is mounted and supported on the bracket and hasa bottom surface, a mounting tab protruding from the bottom surface ofthe base and at least one mounting hole, wherein the bottom surface andthe mounting tab correspond to the top surface and the fastening tab.The mounting hole is formed through the mounting tab. The rail body issecurely mounted on the base.

Other objectives, advantages and novel features of the invention willbecome more apparent from the following detailed description when takenin conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

With reference to FIGS. 1, 2 and 3, a rail assembly in accordance withthe present invention comprises a bracket (10), a base (20), a rail body(30) and at least one bolt (40).

The bracket (10) may be formed by plastic, wood or the like, may be arectangular or a multi-facets straight bar and has an inner surface, anouter surface, a top surface (11) and a fastening tab (12).

The inner surface of the bracket (10) is mounted on a surface (50) of afurniture.

The outer surface is opposite to the inner surface.

The fastening tab (12) protrudes from the top surface (11) of thebracket (10) and has at least one fixing hole (122) and a cross-section.

Each fixing hole (122) is formed through the fastening tab (12).

The cross-section of the fastening tab (12) may be a trapezoid having afirst slope side. The first slope side faces to the surface (50) whenthe bracket (10) being mounted on the surface (50).

The base (20) is mounted and supported on the bracket (10), may beformed by plastic, wood or the like, may be a rectangular or amulti-facets straight bar and has a bottom surface (21), an innersurface, an outer surface and an attaching tab (22).

The bottom surface (21) corresponds to the top surface (11) and thefastening tab (12) of the bracket (10) and may be supported on the topsurface (11) and the fastening tab (12) when the base (20) is mounted onthe bracket (10).

The inner face is attached to the surface (50) of the furniture afterthe bottom surface (21) is detachably mounted on the top surface (11) ofthe bracket (10).

The attaching tab (22) protrudes from the bottom surface (21),corresponds to and abuts with the top surface (11) and the fastening tab(12) of the bracket (10), is mounted between the fastening tab (12) andthe surface (50) and has at least one mounting hole (222) and across-section.

Each mounting hole (222) corresponds to one fixing hole (122) and isformed though the attaching tab (22).

The cross-section of the attaching tab (22) may be a trapezoid having asecond slope side. The second slope side of the attaching tab (22) abutswith the first slope side of the fastening tab (12).

The rail body (30) corresponds to and is securely mounted on the outersurface of the base (20).

Each bolt (40) has a rugged body (42) and a head being coaxially mountedon the rugged body (42).

The rugged body (42) is securely mounted into the corresponding fixinghole (122) and mounting hole (222) to hold the base (20) on the bracket(10) in position and may be threaded or may be formed by multiplehooking rings formed on the rugged body (42).

Take a Ready-to-assemble (RTA) desk as an example, the RTA desk may havea desk body and a drawer. The drawer is slidably mounted on the deskbody with the rail assembly in accordance with the present invention.When a person buys a RTA desk, he/she can get the desk body withassembled bracket (10) mounted thereon and the base (20) with rail body(30) securely mounted on the base (20). Therefore, it is only to placethe base (20) with the rail body (30) onto the bracket (10) and then toinsert the bolt (40) into the corresponding fixing hole (122) andmounting hole (222) to securely hold the base (20) on the bracket (10)without using any tool.

Even though numerous characteristics and advantages of the presentinvention have been set forth in the foregoing description, togetherwith details of the structure and function of the invention, thedisclosure is illustrative only. Changes may be made in detail,especially in matters of shape, size and arrangement of parts within theprinciples of the invention to the full extent indicated by the broadgeneral meaning of the terms in which the appended claims are expressed.
